range is made up from actual specimens observed. The inclusion 
of localities based on published records, which in many cases give 
either no description at all or one so scanty that it is impossible to tell 
whether the var. villosus or E. arenarius is the subject, would merely 
continue the confusion which has so long existed between these two 
plants. 
From three localities on Puget Sound are collections of a plant which 
is allied to E. arenarius, var. villosus because of the pubescent summit 
of the culm and the nerves of the glumes, but the spikelets are longer, 
stiffer, often 5-8-flowered, and borne on definite pedicels which are 
often prolonged and branched, bearing several spikelets. Elymus 
arenarius, f. compositus Abromeit, although I have seen no specimens, 
seems to be a perfect match for this well marked plant from the-State 
of Washington, because of the points clearly mentioned in the original 
description. “Die Ahren entwickeln im unteren und mittleren Teile 
statt der 3-4 blütigen Ahrchen gegen 4 cm. lange und etwa 8 blütige 
Seitenüste. Beobachtet: Bei Kome [Greenland] unter normalen Ex- 
emplaren der Form £ villosus.” This unusual plant may be known as 
ELYMUS ARENARIUS L., var. compositus (Abromeit), n. comb. Æ. 
arenarius L., f. compositus Abromeit, Bibliot. Bot. viii. heft 42, 96- 
(1899). The following North American stations are known: Wasn- 
INGTON: on sandy ground, shore of Bellingham Bay, July 17, 1890, 
W. N. Suksdorf, no. 1028; on high sea beaches, Fairhaven, July 2, 
1897, C. V. Piper, no. 2606; Everett, July 7, 1904, C. V. Piper, no. 
4909. 
A noteworthy plant of this group of awnless, broad-glumed, mari- 
time species has been collected along the sea coast at Westport, 
California. Like E. arenarius of Europe it has the summit of the 
culm perfectly glabrous; and. like the var. villosus of the American 
continent it has the glumes prominently ribbed, but it differs from 
both in having the lemmas glabrous at base, pulverulent above, in 
having a smaller grain (5 mm. long), and a smaller anther (1.5 mm. 
long). Because of its marked differences from these near relatives 
itis proposed as 
Ervwvus strigatus, n. sp., caespitosus perennis 2.5-4 dm. altus, 
culmo paullum striato glabro, vaginis laxis profunde striatis, strigis 
cellulari-reticulatis, ligulis brevissimis (1 mm. longis), laminis lineari- 
bus (4-14 em. longis, 2-6 mm. latis) gabris profunde striatis, spica 
6-11 em. longa, 6-10 mm. lata, spiculis appressis vel geminis vel 
solitariis ad basim spicae 1-3-floris, flosculo supremo sterili, glumis 
lanceolatis (10-15 mm. longis, 1.5-4 mm. latis) cum nervis 4-7 promi-
